LAMP-BURNER.

$PECIFICATION forming part of Letters Patent No. 726,247, dated April28, 1903.

Application filed March 10, 1902 Serial No. 97,551. (No model.)

To all whom it may concern.-

Be it known that 1, WILLI M LUTHER- Bo-; GLE, a citizen of the UnitedStat es,'residing at Columbus, in the county of Lowndes and State ofMississippi, have invented a new and useful Lamp-Burner, of which thefollowing is a specification. 1 A

This invention has for its object the production of a lamp-burnerwherein the lamp- [0 chimney will be self-adjusting or self-adapting tothe holding means, whereby the work of placing the chimney upon theburner is greatly simplified and the danger of breakage minimized.

Another object of the invention is the production of a burner containingcertain novel features of construction, all as hereinafter shown anddescribed, and specifically pointed out in the claims.

In the drawings illustrative of the invention, Figure 1 is a transversesectional elevation. Fig. 2 is a perspective view of the burner with thebell member elevated. Fig. 3 isa detail view of a slightly-modified formof looped spring.

The burner frame or shell is formed with an outwardly-extended flange 5at its lower edge, a vertical portion 6 rising therefrom,

and a horizontal portion Z merging into the vertical portion by a curvedportion 8. At the center the shell is formed with an upwardly-risingdome 9, and surrounding this dome a short distance therefrom is anannnlar rib 10, whereby an annular channel is formed around the dome, asshown. Depending centrally from the under side ofvthe shell is a rib 11,having an annular channel near its lower part.

The wick supporting portion 12 of the burner is of the usualconstruction and is supported by the dome portion 9, as shown.

Formed radially through the rib 10 and portions 5, 6, 7, and 8 of theshell are recesses or open slots 13, in which fiat spring mem- 5 hers 14engage, conforming; substantially to the outline of the parts 6 and 7,but projecting beyond the outer surface of the vertical portion 6, asshown. The upper ends of the springs 14: extend into the channel formedby the rib 10 and the dome 9 and are securedto a ring 15, fitting thischannel and supported thereby, as shown. The lower ends of-the springs14 are extended inward beneath the fi-ar'ne'and engaged by a ring 17,which is supported in the channel in the rib 11. By this means thesprings are securely supported upon the frame at both their upper andlower ends" The springs may each be constructed of a single piece bentto the proper shape (see Fig. 1) or in two parts united, as by rivetingat 18, (see Fig. 3,) as preferred.

The flame-protecting bell is of the usual construction and isrepresented at 19 and secured to the shell just' outside the rib 10,which forms the support for the bell, as shown.

The chimney is of the usual structure and is represented at 20 and willbe engaged by the springs 14 and by the vertical portion 6 of the frameor shell.

The vertical portion 6 of the shell or frame, with the rounded upperportion 8 whereby the portion 6 is merged into the horizontal portion 7,is an important feature of the invention, as it enables the chimney tobe placed in position upon the burner without the necessity of adjustingit to the holding means,

as'in ordinary burners, as the chimney will readily adapt itself to therounded form of the shell andwill not be affected by any protrudingportions of the holding means, as the ends of the holding-springsareentirely inclosed beneath the ring 15. Thus in placing the chimneyupon the burner no care need be taken to locate or adjust it, as it willfind its own seat upon the flange 5 and will require the use of but onehand to engage it. On the other hand, the part comprising thechimneysupporting shell or frame, being loosely mounted upon the partcomprising the wick- 0 supporting means, will enable the framework andthe chimney carried thereby to be removed from the wick-supportingportion in the same manner as with the ordinary burner.

The ring 15'will be of non-heat-conducting material and will becomparatively large in cross-section, so that the surrounding materialof the shell and the springs will be protected somewhat from the heat.

Having thus described my invention, what rco I claim is- I 1. In alamp-burner, a shell or frame having a lateral chimney-supporting flangeand an upwardly-contracted chimney-seatingportion rising therefrom andprovided with radial slots, and looped springs having spaced fixedextremities, extending downwardly within said slots and having freeintermediate portions.

2. In a lam p-burner, a shell or frame adapted to support the chimneyand having a laterally-extended flange and horizontal top, a verticalside portion merging by curved lines into said horizontal top, andhaving radial recesses in said vertical portion, a ring concentricallydisposed on said shell or frame and springs connected to said ring andoccupying said recesses, and alfording a support to the chimney,substantially as described.

3. In a lamp-burner, a shell or frame adapted to support the chimney, aring of heat-nonconducting material concentrically disposed upon saidshell or frame, springs radially dis posed upon said frame and attachedto said ring and alfording a support for the chimney, substantially asdescribed.

4. In a lamp-burner, a shell or frame having a laterally-extended flangeand a horizontal top, a vertical side portion merging into saidhorizontal top, radial recesses in said side portion, a ring centrallydisposed above said horizontal top, a ring centrally disposed beneathsaid horizontal top, and springs connected at their ends to said ringsand seated in said recesses, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two witnesses.

WILLIAM LUTHER BOGLE.
